The feed tube for the gun has an inlet with an outlet transverse to the inlet and which is adapted to be coupled to the ball inlet of the gun barrel. The feed robe wall opposite the outlet effectively is closed. The feed tube also has a gas outlet in the feed tube opposite its outlet for directing gas toward the feed tube outlet for enhancing movement of a ball in the feed tube out of its outlet into the gun barrel.

An apparatus to be attached to a gun of the type having a bore with a ball inlet for allowing balls to pass into said bore, comprising: a feed tube having a passageway extending between a tube inlet and a tube outlet with said tube outlet adapted to be aligned with the ball inlet of the gun for allowing a ball to pass from said tube inlet to said tube outlet by way of said passageway and into the bore of the gun by way of the ball inlet, said tube inlet being generally transverse to said tube outlet with first and second transverse wall portions of said passageway facing said tube outlet and said tube inlet respectively, such that a ball passing from said tube inlet through said tube outlet will follow a transverse path, a gas outlet means formed in said first wall portion of said feed tube for directing gas toward said tube outlet for enhancing movement of a ball in said passageway between said gas outlet means and said tube outlet through said tube outlet, a channel formed in the structure of said feed tube leading to said gas outlet, said channel having a channel inlet located away from said first wall portion, said gas outlet means being the only passage formed in said first wall portion. A gun for firing balls, comprising: a barrel having a bore with a ball outlet through which balls are to be fired and a ball inlet for allowing a ball to be located in said bore, pressurized gas means coupled to said gun for providing gas under pressure, means for applying gas under pressure from said pressurized gas means into said bore for forcing a ball in said bore out of said ball outlet, a feed tube having a passageway extending between a tube inlet and a tube outlet with said tube outlet being aligned with said ball inlet of the gun for allowing a ball to pass from said tube inlet to said tube outlet by way of said passageway and into said bore of the gun by way of said ball inlet, said tube inlet being generally transverse to said tube outlet with first and second transverse wall portions of said passageway facing said tube outlet and said tube inlet respectively, such that a ball passing from said tube inlet through said tube outlet will follow a transverse path, a gas outlet means formed in said first wall portion of said feed tube for directing gas toward said tube outlet for enhancing movement of a ball in said passageway between said gas outlet means and said tube outlet through said tube outlet, and means for applying gas under pressure released from said pressurized gas means to said gas outlet means.
